To all whom it may concern: 7

,Be it known that I, F RED S. FULLER, a citizen of the United States, residing at Eaton, in the county of Weld and State of Colorado, have invented certain new and useful Improvements in Sack-Holder Attachments for Potato-Sorters, of which the following is a specification.

This invention relates to new and useful improvements in sack holder attachments for potato sorters and the like.

An object of this invention is the prov1- sion of a device of the above named class which will support a sack or sacks in a convenient position relative to a potato sorter and in such manner that they can be readily removed without danger of injury to the operator.

Another object is the production of an attachment for the purpose described which will hold the mouths of various sized sacks in their extended positions.

A further object of this invention is to improve and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and eflicient in use and readily operated.

In effecting these several desiderata, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of a portion of a conventional form of a potato sorter having my invention applied thereto; Fig. 2 is a top plan view thereof; Fig. 3 is an end view thereof, and Fig. 1 is a horizontal sectional view taken on the line 4c4 of Fig. 3.

Referring to the drawings by similar characters of reference, throughout the several views, the numeral 10 designates a conventional form of a potato sorter, comprising a base 11, from which extend the vertical bars 12 which support the usual sorter frame 13, the adjacent vertical bars 12 are united by a transversely disposed, horizontal supporting bar 16.

A pair of U shaped brackets 17, is attached in any suitable manner to the inner or rear side of the bar 16 and each is formed adjacent the terminals of its bight portion with apertures through which and through openings provided in the said bar 16, extend forwardly diverging sliding rods 18 which are forced normally outwardly by COll springs which surround the same between head 24. Each of said levers 21 is offset between its ends and pivoted to the inter- :me'diate portion of a catch bar 25 the ends thereof being offset and sharpened to produce prongs 27 which are slidably located in eyes 26 located at either end of the said bar 16. These prongs 26 serve to engage the opposite side of the sack mouth to the one engaged by the hooks 19.

Bars 28 formed preferably of angle material are secured to the ends of the bar 16 and have springs 29 connected thereto, which springs are also connected to the levers 21 serving to normally force the same upwardly retaining the prongs 26 in their uppermost positions. Wear plates 30 are secured to the front faces of the bar 16 in the rear of the levers 21, and are offset at their lower ends producing stops 31 which limit the downward movement of the said levers to an extent that will prevent the dis engagement of the prongs 26 from the eyes 27.

A sack is applied to the device as follows: One edge of the mouth of the sack 20 is engaged by the prongs 26 after which the rods 18 are forced inwardly against the tension of the coil springs until the hooks l9 engage the opposite side of the sack mouth. This obviously retains the mouth in an open position and permits the opposite end of he sack to rest upon the base 11.

l/Vhen it is desired to release the sack, all that is required is to force the proper lever 21 downwardly causing the prongs 26 to drop through the eyes 27, obviously freeing the same from the sack.

From the foregoing disclosures taken in connection with the accompanying drawings it will be manifest that a sack holder attachment for potato sorters is provided for which will fulfil all of the necessary requirements of such a device, it of course being understood that various minor changes in the detalls of constructlon can be resorted to Within the scope of the appended,

movable therethrough, hooks upon said rods,

a lever pivoted to the said bar, a sliding bar operated by the lever, prongs formed upon the ends of said bar, and guides engaging the prongs.

2. The combination With a bar, of a bracket secured thereto, rods movable through the bar and bracket, a lever pivoted to the bar, a sliding bar operated by the lever, prongs formed upon the sliding bar, eyes secured to said bar surrounding the prongs hooks upon the rods, a Wear plate for the lever, and a stop provided upon the Wear plate for the lever.

3. The combination With a frame bar, of a bracket secured thereto, rods passing through the bracket and bar, hooks upon the rods, springs engaging the rods, a lever pivoted to the bar, a sliding bar carried by the lever, prongs formed upon the sliding bar, eyes carried by the frame bar and engaging the prongs, a Wear plate for the lever, a stop formed upon the Wear plate to limit the movement of the lever, and springs engaging the lever substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

FRED S. FULLER.
